Specifications
Main Input Power - TB3 Terminals 3(-) and 4(+)
Filtered 19.1 - 26.4 VDC, 4.2 amps maximum, supplied by an FACP or remote power supply UL listed for Fire
Protective Signaling Service, such as the FCPS-24F(E). See Appendices for compatibility chart and wiring dia-
grams. Use battery calculation tables in Appendix A to determine the actual current requirements. Note: W hen
using power from the host FACP or a remote power supply, the FIRE•COMMA ND•25/50 power requirements
must be included in the FA CP or remote power supply battery calculations.
CAUTION: W hen optional FC-PSM(E) Power Supply/Battery Charger Module is installed, do not connect exter-
nal power to Terminals 3 and 4. Terminals must have no wiring connected to them.
TB3 Terminals 1(-) and 2(+)
Future Use - Do not connect to field wiring.
Optional Internal Power Supply/Battery Charger FC-PSM(E) - Plugs into P7 of the main circuit board
AC Power - TB1 of Optional Power Supply/Battery Charger Module
FC-PSM Power Supply/Battery Charger Module: 120 VAC, 60 Hz, 1.0 amp.
FC-PSME Power Supply/Battery Charger Module: 220/240 VAC, 50 Hz, 0.5 amp.
Wire size: minimum #14 AWG with 600 V insulation.
AC Loss Relay - TB2 of Optional FC-PSM(E) Power Supply/Battery Charger Module
Operation: Relay transfers on loss of AC power to the Power Supply/Battery Charger Module for independent
monitoring by DACT.
TB2 AC Loss relay contact rating: 2.0 amps @ 30 VDC (resistive), 0.6 amps @125 VAC (resistive)
Battery (lead acid only) - P2 of Optional FC-PSM(E) Power Supply/Battery Charger Module
Maximum Charging Circuit: Normal Flat Charge - 27.6V @ 0.800 amp
Maximum Charger Capacity: 17 Amp Hour battery. (FIRE•COMMAND•25/50 cabinet holds maximum 7 Amp
Hour Battery. Larger batteries require Fire•Lite #BB-17F or other UL listed battery cabinet).
Command Input Circuits - TB2 Terminals 3(+) & 4(-) and TB5 Terminals 3(+) & 4(-)
CMD1 and CMD2 Command Input Circuits on Terminals 3 and 4. Terminal 1(-) and 2(+) are output terminals
which provide feed through of the NAC circuits to NAC devices downstream.
Power-limited circuitry
Operation: Both circuits independently field programmable to activate amplifiers on NAC polarity reversal or
contact-closure.
Normal Operating Voltage: 10.5 - 29 VDC (UL tested range: -15%, +10%)
NAC Reverse Polarity Current: 1.6 mA maximum.
Contact Closure Operation Current (requires 4.7K, ¼ watt End-of-Line Resistor P/N 27072): 6.6 mA maximum
Standby Current: n/a
Audio Amplifier Module - Standard Amp plugs into P4 of main circuit board, optional Amp (FC-AAM25)
plugs into P3 of main circuit board
Backup Audio In - TB2, Terminals 1 & 2 (Out Terminals 3 & 4)
Operation: Optional amplifier provides backup to standard amplifier. Switch S1 on the backup amplifier must be
'ON' and jumpers placed from backup amplifier TB2 Terminal 3 to standard amplifier TB2 Terminal 1 and from
backup amplifier TB2 Terminal 4 to standard amplifier TB2 Terminal 2. Refer to Chapter 5 for additional infor-
mation.
